ments in the composing and assembling mechanisms of the line-casting machines known commercially under the trade mark Linotype.

The accompanyin ferred constructionaj vention.

Figures 1 and 2 are side elevations from the right hand side of the machine, and Fig. 3, a detail front elevation of the imroved means for locking a magazine and its frame in their raised position; Figs. 1 and 5, side elevations from the right-hand side of the machine, and Fig. 6 a detail plan, together illustrating the improved construe tion'of assembler entrance. Fig. a sectional side elevation from the rig...-hand side of the machine, of the improved key figures illustrate preforms of the said inboard cam-carriage.

Referring to Figs. 1 to 3, 18 is a matrix or type die magazine carried by frame 19, and 20, 21, two rods extending transversely of the machine frame and on which the magazine frame 19 rests. In removing the magazine from the machine, it is usual to raise its front by cams, to disengage it from the matrixescapement mechanism. The object of the improvement is to lock the said front in its raised position, so as to prevent a sudden jar accidentally making it drop down upon the machine. The mechanism for accomplishing this object, is the same on both sides of the machine and is as follows: 22 is a lever on the outer end of the rod 20; 23, a bent link pivoted to the frame 19 at 32 behind the rod 20 and having a nose 2 1; and 25, a flat plate fast on the rod 20 by the side of the link 23. When the magazine 18 and its frame 19 are down upon the machine frame, the nose 2 1- and plate 25 project to the rear, as shown in Fig. 1. 27

is a stud parallel with the rod 20, projecting from the bend in the link 23 and connecting it pivotally with the plate 25; 28 a bolt working in a socket 29 in the'link 23 be tween the nose 24 and the stud 27, and constantly urged by a spring 30 toward the plate 25; and 31 is a socket in the latter for the bolt 28 to engage in so as to lock the magazine 18 and its frame 19 in their raised position whenever a magazine is to be quick changed. To IfllSO the magazine 18 and its frame 19, the operator rocks the levers 22 from the position shown in Fig. 1, into that of Fig. 2. \Vhen both magazine and frame are in the raised position, the nose 24 is hearing against the red 20, the pivot 27 has moved from behind the rod 20 to the front of it, the said bearing being then on one side of a line drawn through the pivot 32 and the rod 20 and the pivot 2'7 on the other side, the socket 31 registers with the bolt 28 and the spring 30 makes the latter engage in the said socket, whereby both magazine 18 and its frame 19 are securely locked in their raised position. It will be observed that according to the construction illustrated, the rod 20 is de Jendcd on for two functions, (a) to be theaxis of the lever: 22 and (b) to stop the links 23 by standin in the path of their noses 24-. Ncvertheles the invention is not limited to both the functions being discharged by the rod 20 the stop may be of any suitable type dis tinct from this rod. Instead of there being a lever 22 on each side of the frame 19, there may be only one, and it may be on either side.

Referring to Figs. l to O, 33 is the assembler entrance back plate and 34, one of its vertical ribs; 35, a plate not of cast metal as slotted and held behind the plate 35, its slots registering with those in the plate 85,

eaaoeo by a distance piece 40'and screws 4:1 passed I verse axis, a link ivoted to the supporting through both bar 39 and distance piece 4a .The-usual rearwardly bent tops 4201f the ribsB-i, are passed through the'respective air of slots in the plate 35 and the bar 39 ehind it, and fixedthere by a rod passed through the'holes 43 in the said tops.

Referring to Fig. 7, 4:4: is a key lever" {l5 its pivot, and 46 an escapement rod. 4 is a key rod engaged byits key lever 44, en-

. gaging a be1l-crank lever 48 turning on a stationary fulcrum 48, and made, by' its key rod 47, to hold the respective endofa lever 4:9 or so-called cam-carriage, fulcrumed on a fixed point 50011 the maohme frame 51, in engagement with its esoapement rod $6; 52, a cam pivoted on its cam carriage l9; and 53, a constantly running roller, supported at a short distance below the series of cams 52. The depression of a key lever 4.4 rocks'the topend of the respective lever 48 from under the solid end of the respective carriage li), whereupon the latter drops until its cam 52 rests upon the roller 53. The latter turns the cam through one revolution, thereby raising the escapement rod 46 and causing it to release a matrix from the magazine. Experience with the construction just described, has shown that there is enough wear between the cam carriage 4:9 and its escapement rod 46, to practically shorten the rise of the latter and thereby thwart its matrix-delivering action. According to the present invention the cam carriage is reversible both end for end and side for side, so that four difierent surfaces may be brought into position to contact with the rod 46. This reversibility of the cam carriage is conveniently effected by forming pivot holes and Y54 in both ends of the same, which holes are midway between the upper and lower faces of the carriage, as well as being equallyspaced from the axis of the cam 5 Having described my invention, I declare that what I claim and desire to secure by Letters Patent is 1. In a line castingmachine, the combination of the main frame, a magazine supporting frame movable up and down thereon; a lever pivoted tothe supporting frame, a plate pivoted to the lever and to the main frame and adapted when rocked in-or'ie direction to raise the lever and elevate the supporting frame, a socket in the plate, a locking bolt carried by the lever and adapt ed to enter the socket in the plate, the said lever being provided with a nose adapted when raised to engage a fixed stop on the main frame, and means for rocking theplate.

2. In a line casting machine, the combination of the mainframe, a magazine support frame and pivote also to the plate, Whereby' when the plate'is rocked, the link will be raised and will elevate the supporting 4 frame, and a sto on the main frame adapted to be engag by the link when the latter is raised, the relation of the pivotal axes of the late and link being such that when the lin is raised, its pivotal connection with the plate will be to one side of a line intersecting thepivotal axis of the link with the supporting frame and the. stop on the niain frame, andv means for rocking the p ate.

3. In a line casting machine, the combination of the main frame having a stop, a magazine supporting frame movable up and "down thereon, a plate pivoted to the main frame, a link plv'oted to the supporting frame and to the plate and provided with a surface ada ted to coiiperate with the stop,

and means or rocking the plate.

4:. In a line casting machine, an assembler entrance having a back plate provided at intervals in its upper end with notches to receive the assembler guides, in combination with a bar extending at the rear of the back plate and spaced therefrom and provided wlith notches alining with those in the back ate.
